Singlespeed & Fixed Gear "I still feel that variable gears are only for people over forty-five. Isn't it better to triumph by the strength of your muscles than by the artifice of a derailer? We are getting soft...As for me, give me a fixed gear!"-- Henri Desgrange (31 January 1865 - 16 August 1940)

running f/f with different sizes; how big a difference can you go?

If you are not looking to change chains, or have your wheel fall off, as a real approximate, how many tooth difference can you run of a flip/flop hub?
I'll guess that one or 2 is ok, providing you have the room in your dropouts, but 3 or more? does anybody ride like this? I'm thinking of getting a slightly smaller freewheel, and bigger cog, maybe 2 teeth difference.

My friend had a 15 tooth cog on his bike, and I helped him to replace it with a 18t one.
We did not have to resize the chain, it was perfect.
I guess the tooth difference is 3-4 max, depending on your track ends/dropouts ...

The distance the axle moves in the dropouts is 1/8" for each tooth difference, so for a 3 tooth difference you will need at least 3/8" horizontal length in your dropouts

16 and a 13 on my bike. I used to have an 16/18 and didn't need to resize the chain (although I swapped my 46 chainring for a 47 at some point, so an 18 probably won't fit anymore).

I can run between 15 and 19t on mine. I think I might be able to go one more tooth either way too, and no super long dropouts, just the regular dropouts on a Soma Rush.

I went from 16 to 19 on mine fine. The only thing is that you have to deflate the rear tire to get the chain and wheel off now because it's so close to the seat tube.

i could do 20/16 alright. 20 was way in front of the dropout of course, almost as far as it could go. im sure i could have gone to 15 if i had it...
